Apple’s lead over Samsung in the U.S. widened in April

FORTUNE — Google’s GOOG Android, at 52%, took the largest share of U.S. smartphone sales in the three month period (Jan. – Mar.) covered by comScore’s report Friday. But it managed to lose 1.4 percentage points sequentially, while Apple AAPL, at 39%, gained 2.7.

In the Apple vs. Samsung competition, Apple widened its U.S. lead, which now stands at 39% to 21.7%. But as Brian Loftus’ chart above shows, Apple is not widening that lead quite as fast as it had been in recent months.
